Morphometric Analysis of Different Parameters for Labeo boga from Head Panjnad, Alipur, Punjab, Pakistan

Abstract

This study was designed to analyze the external morphometric characteristics of Labeoboga from Head Panjnad, Alipur, Punjab, Pakistan. About 48 specimens were collected and examined to address the growth patterns of the species under study for the first time, together with their morphometric characteristics for the analysis of morphological characters. The analysis of the present results for the length-weight relationship revealed that the value of regression coefficient ‘b’ was <3.0 according to the cube law, showing a negative allometric growth pattern (b = 2.710). Additionally, a highly significant positive correlation (r > 0.931; P < 0.05) was recorded for the correlation value ‘r’ among weight and length. A linear correlation was observed among 11 morphometric characters vs total length (TL), which revealed a highly significant correlation between total length vs standard length, body weight, fork length, dorsal fin length, body girth, body depth, anal fin length, and pectoral fin length, respectively. While, a moderate correlation was recorded between total length vs head length, eye diameter, and caudal peduncle length. Furthermore, the same trend was observed in the correlation significance between total body weight and other morphometric characters. The current study would be helpful for ichthyologists and zoologists in comparing different morphometric characteristics of Labeoboga.
